Sink or Float Pond

How to play

Your child runs real little experiments: an object hangs over a pond, they predict "Float" or "Sink", and then it drops in and does exactly what it would in real water, from an ice cube that floats with most of it hidden below the surface to a stone that settles on the bottom. A wrong guess is celebrated as a surprise discovery, with a short, true explanation like "It is small, but metal is heavy for its size", so children learn that size alone doesn't decide, and that wood floats, solid metal and stone sink, and things full of air float. Levels move from everyday objects to surprises like a big log, a giant pumpkin and a tiny coin, then to sorting by material and a mixed pond where even a metal bowl floats because of its shape. There are no timers and no losing: every experiment brings a lily, fish or frog to the pond, and each finished level earns a star.
